Giant cell tumor of patella: A case report and review of literature
Journal of Emergency Practice and Trauma
Objective: Patella is a sesamoid bone which develops in the quadriceps tendon. It is an uncommon site for neoplasms. The most common primary tumors which involve patella are benign. These include chondroblastoma, giant cell tumor (GCT) and aneurysmal bone cyst. Malignant lesions are less common in patella. These encompass metastasis, osteosarcoma and hemangioendothelioma. The most common complaint in patients of GCT patella is anterior knee pain. Early diagnosis and optimal management are necessary for improving survival rate in these patients. Case Presentation: The authors present a case report of GCT of patella in a 16-year old child. Incisional biopsy was done to confirm the diagnosis. Further radiological examination showed that the tumor involved almost whole of the patella. Hence, surgical management in the form of patellectomy and extensor mechanism repair was done to improve the outcome of the disease. The patient did not have any clinical or radiological symptoms at the en...
Patellar Giant-Cell Tumor: a Case Report
The Journal of Experimental Life Sciences
Giant cell tumor (GCT) found mostly in the long bones metaphysis or epiphysis. GCT usually occur between the ages of a third and fourth decade and locally aggressive. Giant-Cell Tumor seldom affects the patella. Multicentric forms rarely reported. A fourteen-year-old female with a lump at her left patella since one-year associated with slight pain that aggravated by activity for six months. Plain X-ray left knee AP, and lateral views reveal expansile lytic lesion in left patella with thinning of the anteroinferior cortex and sclerotic septa within. MRI of left knee shows approximately 3x2x2 cm heterogeneous lobulated expansile soft tissue mass in left patella extending up to the patellofemoral joint with fluid-fluid appearance. From fine needle aspiration cytology, resulting giant-cell tumor with the differential diagnosis of an aneurysmal bone cyst. The operation already performed. Curettage, bone graft, and a biopsy taken. An immunocytochemical smear was performed and confirmed as a patellar giant-cell tumor. Six months after excision of the tumor, the patient complained no arthralgia and have a full range of motion for the knee.
Giant Cell Tumor of the Patella: An Uncommon Site
Nepalese Journal of Radiology, 2018
Primary tumors of the patella are rare of which Giant cell tumor is the most frequent. Patient usually presents with pain in anterior knee and swelling. Radiologically, Giant cell tumor usually presents as a well defined lytic lesion with no sclerotic margin, no periosteal reaction and no soft tissue involvement unless complicated by fracture and shows enhancement on post-contrast study. Herein, we report the case of a 31-year female with giant cell tumor of the patella (GCT) with its clinical and radiological features.
Giant-Cell Tumor of the Patella: Case Report
The Journal of medical research, 2018
Giant cell tumor (GCT) is a tumor found most often in the ends of long bones and is essentially located in the epiphyseal or metaphyseal or epiphyseal equivalent portions of bone. It is a locally aggressive neoplasm, generally arising in adults between the ages of 20 and 40 years, clinically possessing metastatic potential. The classic location is around the knee joint and it starts in the epiphysis spreading to the metaphysis and may erode the cortex in 25% of the cases. Approximately 10% of these tumors have a malignant course. The patella is a rare site with a reported incidence of less than one percent. Rare multicentric forms have been reported. A 14-year-old female from Malang, East Java, presented with a one year history of a progressively growing mass in the left patella associated with slight pain that has been aggravated with activity for 6
Secondary aneurysmal bone cyst of the patella
Acta Orthopaedica et Traumatologica Turcica, 2010
Aneurysmal bone cyst accounts for 1% of primary bone tumors and is one of the benign tumorlike lesions. Patellar involvement is quite rare. Its development on the basis of any previous lesion such as chondroblastoma is called secondary aneurysmal bone cyst. A 26-year-old male patient presented with right knee pain of three-year history. Physical examination showed a firm, immobile swelling at the anterior aspect of the right knee, without increase in temperature or redness of the skin. There was no pain on palpation and joint range of motion was normal. Radiological studies were suggestive of an aneurysmal bone cyst. At surgery, the cystic lesion was removed via curettage and the residual cavity was filled with an autogenous bone graft taken from the iliac wing. The histopathologic diagnosis was secondary aneurysmal bone cyst in association with chondroblastoma. During a 1.5-year follow-up, the patient had no complaint and no recurrence was observed.
A Rare Case Report on Primary Aneurysmal Bone Cyst of the Patella
International journal of current research and review, 2020
An aneurysmal bone cyst is a benign tumour with unknown pathophysiology as described by Jaffe and Lichtenstein 1. ABC most commonly presents during their second decade of life and mostly involves metaphysis of long bones, followed by spine and sacrum and smaller bone involvement is usually rare. Although benign, the ABC can be locally aggressive and can cause extensive weakening of the bony structure and impinge on the surrounding tissues. It comprises of less than 1-2% of all tumours originating from bone.2-5. Development of Aneurysmal cyst in the patella is rare (<1%).6-9 Exicision alcurettageofthecystandfilling of the defect with a bone graft or cementing 10-13 is the treatment of choice. Treatment with adjuvants such as phenol and cryotherapy is also advised by some studies. 14-16 Embolisation or patella ectomy is considered in significant involvement of the patella with articular surface destruction. 17-19 We, hereby, report a rare case of a primary aneurysmal bone cyst of t...

Giant cell tumor of bone also known as osteoclastoma is a distinct clinical, roentgenographic and pathologic entity with speci•c characteristics. It is a benign but locally aggressive neoplasm of the epiphyseal or metaphyseal-epiphyseal region of long tubular bones extending to the articular surface. It usually occurs after skeletal maturation and is one of the rare bone tumors that more frequently affects women. We report here a case of giant cell tumor originating from the right patella diagnosed on •ne needle aspiration cytology.
Aneurysmal bone cyst of the patella-A case report
Primary tumours of the patella account for less than 0.06% of bone tumours and metastatic lesions are even rarer. Aneurysmal bone cyst (ABC) accounts for 1% among primary bone lesions, and its occurrence in the patella is very rare. Twenty one year old male presented to orthopaedic OPD with complaints of swelling and pain in left knee since one year with increased pain and episodic fever since 3months. There was a history of minor trauma of left knee a year back which healed without any complications there was no other relevant past history. On radiological examination which included x-ray, CT and MRI revealed an osteolytic cystic lesion of patella and provisional diagnosis of aneurismal bone cyst of Patella made and bone curettage was done. On clinic-radiological and histopathological correlation diagnosis of primary ABC of patella was made. The mainstay of treatment of ABCs is intralesional curettage with locally applied adjuvant such as liquid nitrogen or phenol. Other options include enbloc dissection or selective arterial embolization. Young age and open physes are associated with an increased risk of local recurrence. Hence close follow up of patient has to be made.
